The off-throttle is on it's way out so the playfield is even. I think the engine will give them a little boost but it's gonna be uphill battle. Latest rumours state that Kimi is in the "top slot" for driving next year for them. Christain Wolf said in an interview with Austrian paper that "the documents are in the table" and that it is not a publicity stunt like Renault did last year (source:Iltasanomat).
Bad news is of course the fact that Iceman is not a very good communicator.. Typical Finnish male, don't talk and when he does it's short and straight to the point. There's not a lot you can read from his bodylanguage, combine that with the unability to smalltalk (not a part of our national heritage, small talk is not encouraged here..) and the team may feel cold and alienated. But boy, is he fast?
In any case, Williams won't be on the podium any time soon unless they can work some miracles in the next few months. I like Barrichello, a lot, one of the best guys out there, very sweet guy. But he's been too long out of the top fights, time to retire, me thinks.
